I have a question like this:
1) Liza and Tamar leave the same camp and run in opposite directions.
Liza runs 2m/s and Tamar runs 3m/s. How far apart are they after 1 hour?
What I did was:
Liza
----
Have to convert from Sec to hours.
3600 = sec in hours
(2m/s)(3600)=7200 M/H
Now I converted it to KM:
7200M = 7.2KM
So she would be 7.2KM
Tamar:
------
(3M/S)(3600)=10800M/H
Converted to KM
10800 = 10.8 KM
They all together would be 18KM apart.
Right?

What about this:
4) Jon and Jennifer start at the same point and ride their bicycles in
the same direction. Jon travels at 12km/h, while Jennifer travels at
16km/h. After 6h, how far apart are they?
What I did was:
Jon
---
D=Vt
D=(12)(6)
D=72KM
Jennifer
--------
D=VT
D=(16)(6)
D= 96KM
96-72 = 24 Km apart
Is this right? I think I am getting the hang of this.
